That is a bit hard - by simply looking at the message, you cannot tell -
you need to check the state within opensips's register table by using
the registered() function (see
http://www.opensips.org/html/docs/modules/1.6.x/registrar.html#id271187)
- the function will tell if the user is already registered with opensips.

Bogdan
